Halliburton commissions LNG retrofit for RoRo combi carrier

The delivery of the retrofitted M/V Hannah Kristina is expected to take place in March 2022. The 101-metre long, 5,850dwt vessel is owned by Base Marine Norway AS and under technical management by Larvik Shipping AS and operates along the Norwegian coast.

Høglund will collaborate with long-time partners HB Hunte Engineering GmbH and Fiskerstrand Verft AS for the naval architecture and shipyard elements of the project, respectively. The entire project will be classed by DNV.

The scope of work under the contract consists of a 250m³ capacity storage tank and Fuel Gas Supply System (FGSS) with a dedicated Gas Control and Safety System to serve the already installed nine-cylinder 4-stroke dual-fuel engine with natural gas.

As part of the conversion work, which will carried out at Fiskerstrand Verft in Norway, the 20-year-old vessel will also have a shore power connection installed. This will allow the vessel to be powered from the shore while berthing, reducing emissions in port, and to charge the existing 994kWh Energy Storage System (ESS).

As part of the shore power upgrade, Høglund will supply and install a package consisting of shore connection cabinets of 690V / 600kVA compatible with state-of-the-art shore power supply, following IEC80005-3 standards. Both systems will be seamlessly integrated into the existing Automation System (IAS), Power Management System (PMS) and ESS control system of the vessel which were delivered and installed by Høglund in 2018 when the vessel’s ESS was installed.

In order to implement the appropriate safety measures following the requirements of the IGF-Code and improve the safety credentials of the Hannah Kristina, Høglund will be combining its extensive knowledge in gas, power and automation solutions with HB Hunte’s outstanding expertise in naval engineering to perform further modifications on the vessel. These will include the adjustment of the mooring arrangement in the LNG tank area and an upgrade to the ventilation system, among other conversions.

The project has received support from the Norwegian NOx Fund.
